Hello all,
I´m Trying to Run the Minimal-Example of Sensor-Stream API
https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/sensor/stream_drdy#id7
HW is: NRF52840DK, SparkFun Micro 6DoF IMU - ISM330DHCX which is ST, LSM6DSV16X
Code Configuration as follows:
poj.conf
CONFIG_I2C=y CONFIG_I2C_NRFX=y # your &i2c1 instance CONFIG_RTIO=y CONFIG_I2C_RTIO=y CONFIG_GPIO=y CONFIG_SENSOR=y CONFIG_SENSOR_ASYNC_API=y CONFIG_LSM6DSV16X=y CONFIG_LSM6DSV16X_STREAM=y
dts.overlay
&spi0 {status = "disabled";};
&spi1 {status = "disabled";};
&i2c0 {status = "disabled";};
/ {
aliases {
stream0 = &lsm6dsv16x;
};
};
&i2c1 {
status = "okay";
compatible = "nordic,nrf-twim";
pinctrl-0 = <&i2c1_default>;
pinctrl-1 = <&i2c1_sleep>;
pinctrl-names = "default", "sleep";
/*enable device runtime pm for i2c */
//zephyr,pm-device-runtime-auto;
lsm6dsv16x: lsm6dsv16x@6b {
compatible = "st,lsm6dsv16x";
reg = <0x6b>;
status = "okay"; // Ensures the device is active (not disabled)
int1-gpios = <&gpio1 2 GPIO_ACTIVE_HIGH>;
int2-gpios = <&gpio1 4 GPIO_ACTIVE_HIGH>;
drdy-pin=<1>;
accel-odr = <8>;
//gyro-odr = <8>;

//gyro-fifo-batch-rate = <8>;

//zephyr,pm-device-runtime-auto;
};
};
&pinctrl {
i2c1_default: i2c1_default {
group1 {
psels = <NRF_PSEL(TWIM_SDA, 0, 30)>,
<NRF_PSEL(TWIM_SCL, 0, 31)>;
};
};

int rc = 0;
const struct sensor_decoder_api *decoder;

/* Start the streams */
for (int i = 0; i < NUM_SENSORS; i++) {
printk("sensor_stream\n");
sensor_stream(iodevs[i], &stream_ctx, NULL, &handles[i]);
}
while (1) {
printk("Sanity Check Before Consume Block \n");
cqe = rtio_cqe_consume_block(&stream_ctx);
printk("Sanity Check Passed Consume Block \n");
if (cqe->result != 0) {

return cqe->result;
}

if (rc != 0) {
printk("get mempool buffer failed %d\n", rc);
return rc;
}
const struct device *sensor = dev;
rtio_cqe_release(&stream_ctx, cqe);
rc = sensor_get_decoder(sensor, &decoder);
if (rc != 0) {
printk("sensor_get_decoder failed %d\n", rc);
return rc;
}
/* Frame iterator values */
uint32_t accel_fit = 0;
/* Number of sensor data frames */
uint16_t xl_count, frame_count;
rc = decoder->get_frame_count(buf, accel_chan, &xl_count);
if (rc != 0) {
printk("sensor_get_frame failed %d\n", rc);
return rc;
}
frame_count = xl_count;
/* If a tap has occurred lets print it out */
if (decoder->has_trigger(buf, SENSOR_TRIG_TAP)) {
printk("Tap! Sensor %s\n", dev->name);
}
int8_t c = 0;
/* decode and print Accelerometer frames */
c = decoder->decode(buf, accel_chan, &accel_fit, 1, accel_data);
printk("XL data for %s %lluns (%" PRIq(6) ", %" PRIq(6)
", %" PRIq(6) ")\n", dev->name,
PRIsensor_three_axis_data_arg(*accel_data, 0));
rtio_release_buffer(&stream_ctx, buf, buf_len);
}
return rc;
}
When running the example actually does not run into a error but it stucks into the line:
"cqe = rtio_cqe_consume_block(&stream_ctx);"
"
Thats the output when running Program.
I checked already minimal-examples with running the sensor with
- simple sample fetch "polling" and DRDY-Callback on via INT1 GPIO --> Both works without flaws.
Has anybody have had similar cases or can explain what´s potentially causing the issus?
Thank´s already
